PG: Propylene glycol is a derivative of natural gas. It is commonly used in a variety of consumer products and food products, including deodorants, pharmaceuticals, moisturizing lotions, and fat-free ice cream and sour cream products. Ooops, sorry, the wacky chemist in me came out.
In relation to cigars, it is mixed with distilled water (typically 50/50) to create a solution to maintain the humidity level within your humi. A 50/50 mixture maintains 70% relative humidity with itâs surroundings. If the ambient air is over 70% the solution will suck up water from the air, if lower than 70%, the solution will give up water to the air. The PG acts as the water exchange âgatekeeperâ if you will.
Also, when filling the credo it shouldnât be sopping wet. Itâll need some room within the foam to store any extra humidity that it takes out of the air.
